Description

temperature control system

technical field

The utility model relates to a temperature control system, in particular to a temperature control system used in a large storage room to control the temperature and humidity in the storage room.

Background technique

Traditional temperature control systems can be roughly divided into refrigerating/freezing equipment and heating equipment. Usually refrigerating/freezing equipment is used in storage spaces such as freezers. Refrigerating/freezing equipment is used to reduce the air temperature in the storage space to achieve frozen storage such as food Effect. Heating equipment can be used for drying or fruit ripening. The heating equipment heats the air in the storage space, so that for example, pasture can quickly remove moisture, or accelerate the ripening of fruits in a high temperature environment.

In traditional refrigeration/freezing equipment, the temperature of the heat exchange tube may be lower than 0°C. Therefore, when the air with high temperature and humidity in the storage space contacts the heat exchange tube, the moisture will condense on the surface of the heat exchange tube and form frost. When the frost on the surface of the tube is too thick, the heat exchange efficiency between the heat exchange tube and the air in the storage space will be greatly reduced. Therefore, the traditional refrigeration/freezing equipment needs to be defrosted after a period of use. , The refrigerating equipment of the refrigerating/freezing equipment stops operating, so that the temperature of the heat exchange tube rises above 0°C, so that the frost on the surface of the heat exchange tube can be melted into water. However, when the refrigerating/freezing equipment performs defrosting operations, it will not continuously reduce the temperature of the storage space, so the temperature in the storage space will increase significantly during the defrosting period, which may cause a significant drop in the refrigerating/freezing effect, further affecting the freshness of food. have adverse effects. In addition, the heat exchange tube is arranged in the heat exchange device, and a fan is arranged at the outlet of the heat exchange device, and the rotation of the fan causes the air in the storage space to exchange heat with the heat exchange tube to cool down. At the outlet of the heat exchange equipment, negative pressure is generated inside the heat exchange equipment when the fan is running, so when the heat exchange equipment performs defrosting operations, the moisture after defrosting is less likely to be discharged due to the negative pressure inside the heat exchange equipment. outside of the device.

In addition, if the heating equipment is used to dry and remove moisture from items (such as pasture), the moisture in the items will be mixed into the air in the storage space during the drying operation, resulting in an increase in the humidity in the air, further reducing the drying effect , so heating equipment usually requires additional dehumidification mechanism to remove moisture in the air.

For the convenience of description, it is assumed that the temperature control system 10 of the present invention is to be used as a refrigeration/freezing device to control the opening of the first inlet valve 48, the first outlet valve 54, the third inlet valve 92 and the third outlet valve 96, and control the opening of the first The second inlet valve 62, the second outlet valve 68, the fourth inlet valve 94 and the fourth outlet valve 98 are closed. In this state, the first pump 52 is running and the second pump 66 is not running. In this way, only the first heat exchange fluid will Circulating flow between the first storage tank 42 and the first and second heat exchange equipment (20, 70), the refrigerator 46 controls the temperature of the first heat exchange liquid at 10°C~-20°C (the heater 60 does not work ), and the first heat exchange liquid with a temperature of 10°C~-20°C is sent to the first heat exchange tube 30 and the second heat exchange tube 80, and the first and second fans (34, 90) operate to cause the first The first and second blades (28, 78) are pivoted to the open position, and the first and second fans (34, 90) operate to cause the air in the storage space to be heated through the first and second heat exchange tubes (30, 80). After the exchange, the gas is blown out from the first and second gas outlets (26, 76), further reducing the temperature of the air in the storage space.

Assuming that when the surface of the first heat exchange tube 30 of the first heat exchange device 20 is frosted and needs to be defrosted, the first inlet valve 48 and the first outlet valve 54 are controlled to be closed at the same time, the first fan 34 stops running, and each first blade 28 pivots to the closed position, controls the second inlet valve 62 and the second outlet valve 68 to open simultaneously and starts the operation of the second pump 66, in this state, the operation of the first pump 52 causes the first heat exchange fluid to only A storage tank 42 circulates with the second heat exchange device 70, and since the fourth inlet valve 94 and the fourth outlet valve 98 are still closed, when the second pump 66 is running, the second heat exchange fluid will only flow in the second storage tank.
